JAMES WILLIAM WALKER, OF MONTREAL, QUEBEC, CANADA.

GAS-GENERATING AND HEATING APPARATUS.

Specification of Letters Patent. Patented All". 27, 1918- Application filed February 16,1918. Serial No. 217,696.

To all whom it may concern:

Be it known that I, JAMES WILLIAM \VALKER, a citizen of the United States of. America, residing at 466 Guy street, in the city of Montreal, Province of Quebec, Do-

minion of Canada, have invented certain,

chamber, by any suitable means, preferably from a tank orreservoir and hung up 111 order to give pressure to the same, will inif stantly be raised to a temperature of vaporization, the vapor passing through the burner outlets and immediately igniting, when it mixes with the air.

The generator chamber and burner are preferably provided with asbestos strands intermingled with longitudinal wires preferably three in number. The asbestos strands are covered with a coating of graphite which will prevent, to a large extent, the asbestos from being clogged up with the carbon emanating from the hydro-carbon vapors as Well as preventing the carbon from forming on the outside of the strands.

However, carbon may form, on the inside of the generating chamber as well as on the wires and in order to obviatethis, the tank for kerosene is provided with an independent water chamber in whichwater may be introduced occasionally to clean out the generating chamber and burner.

Adjacent to the gas generating chamber,

and communicating therewith, an oil reservoir is provided so that a steady supply of kerosene may be furnished to the gas generating chamber, once the apparatus is in function.

The fact is well known that generating chambers have already been provided with a plurality of passages, the Walls of which are heat-conductive. The present invention is entirely different and it is to obviate these passages that strands of asbestos are used. These strands of asbestos act as a wick and consequently cause the oil to flow more evenly, which does not occur in the generat ing chambers provided with passages. It is considered that this is a great improvement and one of the main features of the present invention.

The reservoir or tank is preferably constructed in such a way that any detritus formed in the bottom of the tank will remain there and will not reach the retort and burner. A netting or strainer is also pro vided in order to prevent any impurities from oing through into the oil supply pipe." To better understand and describe the in-' vention, drawings are hereto annexed in Which:

Figure 1 1s a side elevation of the apparatus.

Fig. 2 1s a perspectlve view of the tank a portion being broken away..

Fig. 3 is a top view of the tray.

Fig. .4: is a cross section view through the generating chamber on line b?), Fig. 1. V

Fig. 5 is a longitudinal sectional view through the oil reservoir on line AA, Fig. 1.

Fig. 6 is a section through the connecting member and water chamber in the tank.

Fig. 7 is a perspective view of one of the baffle plates.

Fig. 8 is a section of a portion of the burner tube showing the strands of asbestos and wires.

Like numerals of reference indicate correspondingparts 'in each'figure.

In the drawmgs, 1 1s a tank of any suitable shape provided with a hole 2, to receive a hook which may be secured on a wall. 0

is the outlet in which fits the member a.

This member or nut will project inside said tank and is provided with an axial opening 5 which is preferably threaded at its opposite ends, the upper-threaded portion engaging a similar thread on the vertical water 1 tube 6. The said tube 6 is supported at its the said outlet holes 9.

A pipe 11 is threaded in the lower end of said member 4, and 12 is a valve for controlling the oil in the tank. The gas generating apparatus may preferably be placed inside a stove, on the grate, or in the fire box or used otherwise, and consists of a horizontal tube 13, to which is connected at right angles a short tube 14, and 15 is another horizontal tube parallel to the tube 13 and connected at one end to the tube 14:. The tubes 13 and 15 are supported by the short plugged tube 16 which serves as a bracket and may rest in any suitable way on the tray 17. This tray has at one end a boss 18 in which is provided a threaded hole 19 to receive the lower end of the tube 16, and 20 are perforations. The tube 15 is perforated to provide suitable burner openings 21.

At one end of said tube 13 is provided a reservoir 22 for the oil, which is connected to said tube 13 by the T 23, and 24 is a sup ply pipe leading from said tube 13 to said valve 12.

The tubes 13, ltand 15 are provided inside with four asbestos strands 25 covered with graphite intermingledwith a few wires 26, preferably three wires as disclosed in Figs. 4 and 8. The wires are preferably galvanized. As has been above described, the asbestos serves as a wick which will naturally draw the oil and cause an even feeding of the vapor to the burner openings 21.

Baffle plates 22 are secured on said tube 13 above the burner openings 21 to spread out the flames or deflect the same as the case may be, and they eachconsist of a disk on which is secured a tubular member which is adapted to fit on said tube 13, said member being secured to said disk by a screw which is driven through the holes provided therein. In the operation of the invention, the valve 12 is opened just sufficiently to soak with oil the asbestos inside the gas generating chamber and burner and so that a little oil will flow through the burn'eropenings 21, thus priming the asbestos waste or ashes which are placed in the tray 17. The valve is then closed, and oil soaked waste in the tray is ignited to heatthe tubes 15 and 13. Vhen the oil that is in these tubes is vaporized by the heat, it will immediately pass through the burner openings 21 and mixing with the air will ignite. The valve 12 is then turned on again for say a quarter turn and then gradually opened to its full extent.

The flames will strike the deflecting or baffle plates 22, 'ausing them to spread.

After a certain time, carbon may accumulate inside the gas generating chamber and burner, and in order that they may not be clogged, water is thrown into the funnel S which will penetrate into the gas generating chamber while it is hot, thus converting the water into vapor which will decompose the carbon therein and combine therewith, form ing carbon-dioxid, which will pass out through the generating chamber and burner into the burner openings 21.

An important feature of the invention is the asbestos packing in the gas generating chamber. The asbestos does not only act as a porous packing which will cause an even feeding of the oil and gas, but it will prevent the innerwalls oft-he gas generating chamber from peeling under the intensive heat which would clog or obstruct the burner openings, as the asbestos keeps a constant moisture against these walls which will ob viate this. Any other suitable mineral substance could be used in place of asbestos such as sand, with probably equivalent results, but asbestos is here disclosed as being preforable.

lVhat I claim is:

In a gas generating and heating apparatus, the combination; with fuel supply means; of a gas generating chamber in communication therewith, comprising a pair of connected, horizontal pipes disposed one above the other in parallel relation, the lower pipe having a plurality of burner openings; and a filling of intermingled strands of mineral absorbent material and wires within said pipes, said absorbent mate rial serving as a wick to cause even feeding of the fuel and vapor to said openings and also serving to prevent the inner walls of said pipes from peeling.

Signed at Montreal, Quebec, Canada, this 21st day of January 1918.
